To all whom it may concern:

Be it knownthat we, HARRY A. MURRAY and WILLIAM T. DoRMAN, citizens of the United States, and residents of Houston, in the county of Harris and State of Texas, have inventedcertain new and useful Improvements in Internal-Combustion Engines. g Our invention has for its 'ob eCt to 1mprove that class of explosive engines especially adapted to be used in connection with resultin'g'in a properly balanced explosive mixture, insuring economy in fuel consumption, While further keeping the engine cooler than is possible under ordinary conditions.

With these and other objects in view the present invention consists in the combina-- tion, and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit oi the invention.

In the accompanying drawing we have shown a broken portion of a conventionally constructed internal combustion gasolene engine cylinder provided with an attachment embodying our invention.

In our present invention we provide an attachment the use of which eliminates the deposit of carbon upon the cylinder Walls, as well as on the face of valves and seats,

thus eliminating the blowing by piston packing rings.

W e further effect a more efiicient and perfeet gasolene mixture by tapping into the top of the water jacket or other convenient source. The water is not forced by a pump but g-ravitates and is drawn by a vacuum instead. Our system gives a mixture in the carburetor to each, cylinder used, and

supplied byv a distributor conventionally used on any type of engine.

The use of our attachment insures an ex plosive mixture which explodes more readily and with greater efiiciency than is possible under ordinary conditions. Further should the amount of water to form the vapor be in excess of the requirement, the surplus can be readily detected, though if not noticed at once, will do no damage to the Working parts of the engine This We accomplish in running a copper coil with regulating valves around the exhaust pipe a su'fiicicnt number of times to heat the water causing a vapor, the mixture or" which with the explosive gas permits the use of-avery low grade of gasolene or solar oils in the drawings A represents the water "jacket surrounding the cylinder, and B the valve chamber.

Entering the top 9 of the Water'jacket, and communicating therewith, is the valve 4 operated by means or the stern 2 Extending ironithe valve 4 is the heating pipe 6, preferably made of copper which is coiled several times about the exhaust pipe '7, finally being secured to the valve 8. Se-

cured to the valve 8 is the which leads into theintakc pipe 3. The valve 8 is operated by means of the valve stem 10. lihis pipe 3, it is of course under stood, leads from the carburetor. In the drawings the pipe 12 leadsfrom the radiator, while the stems l3 and 14: communicate, respectively, with. the intake and exhaust. valves.

pipe section 5 it is of course understood that the How of.

water is from the Water jacket into the intake pipe 3, as is indicated by the arrows.

The water escapes first through the valve 4,

then flows through the coil pipe sections, and

thenthrough the valve 8, and finally through the pipe section 5 into the disclosed.

Our attachment is simple and inexpensive in construction, both durable and-cilicient in. operation and insurestheinteribr of a cylinder, as well as the'exposed valves and valve seats remaining free from carbon dcposits.

Having thus described ourrsaid invention What we claim as new andsdesire to secur by Letters Patent is: v 1. The combination of thecylinderof at intake pipe 3, as u internal combustion. engine having a *Wat a] horizontal portion jacket provided With water thereto, of an exhaust pipe posite end. with the under side zontal portion of the intake pipe, said pipe at all times containing a supply of Water, whereby Water in the C01l is heated and flows y gravity and accumulates in the bottom al portions of the pipe drawn into the cylinder (1 vaporized With the gas by the suction of the piston, and a manually controlled valve for controlling the Water passing through the. pipe.

2. The combination of the cylinder of an internal combustion engine having a Water jacket provided With means for supplying Water thereto, of an intake pipe having a portion and communicating with the cylinder, an exhaust pipe communi eating with the cylinder, a pipe communicating at one end with the Water jacket and coiled adjacent the exhaust pipe and communicating at its opposite end With the horizontal portion of the inlet pipe, said pipe at all times containing a supply of Water, whereby Water in thecoil is heated and flows into and accumulates in the horizontal por-] tion of the intake pipe to be drawn into the cylinder and vaporized with the gas by the 35 suction of the piston.

'In testimony whereof We aflix our signatures, in the presence of two Witnesses.
